This invention describes a heterogeneous metal bearing material, comprising a host material composed of primary particles agglomerated into secondary particles, and a particulate dopant material, characterised in that the particulate dopant material is homogeneously distributed within the secondary particles of said host material. In particular, the dopant material is TiO2 and the host material is either one or a mixture of NixMnyCoz hydroxide, oxyhydroxide, and oxide, with 0 ≤ x, y, z ≤ 1, and x+y+z = 1. |
